SC-200 Manage a security operations environment Practice Question
This SC-200 practice question tests your understanding of manage a security operations environment. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Exhibit
Refer to the exhibit.
```kusto
SigninLogs
| where TimeGenerated > ago(1d)
| where RiskLevelDuringSignIn == "high"
| where RiskLevelAggregated == "high"
| project UserPrincipalName, IPAddress, RiskLevelDuringSignIn, RiskLevelAggregated
| summarize count() by UserPrincipalName
| where count_ > 5
```
Refer to the exhibit. You have an analytics rule in Microsoft Sentinel that uses this KQL query. The rule is configured to run every hour and alert when the result count is greater than 0. Which type of attack is this rule most likely detecting?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.

A
Privileged account misuse
Why wrong: This would involve specific privileges, not just high-risk sign-ins.
B
Data exfiltration via sign-in
Why wrong: Data exfiltration is not directly related to sign-in risk levels.
C
Account takeover from a new location
Why wrong: That would be a single sign-in from an unusual location, not multiple high-risk events.

Correct answer & explanation
✓
Brute force attack on user accounts
The KQL query counts failed sign-in events (ResultType != 0) aggregated by User, IPAddress, and a 5-minute bin, then filters for users with more than 10 failures. This pattern of multiple rapid failed logins from the same IP against a single user is the classic signature of a brute force attack, where an attacker tries many passwords to guess credentials. The rule triggers when the count exceeds 10 within any 5-minute window, making it highly specific to brute force detection.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Privileged account misuse
Why it's wrong here
This would involve specific privileges, not just high-risk sign-ins.
✗
Data exfiltration via sign-in
Why it's wrong here
Data exfiltration is not directly related to sign-in risk levels.
✗
Account takeover from a new location
Why it's wrong here
That would be a single sign-in from an unusual location, not multiple high-risk events.
The clue word "most likely" in the question point toward this answer.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse 'account takeover from a new location' (which requires a successful sign-in from an unfamiliar location) with 'brute force attack' (which is characterized by multiple failed sign-ins), leading them to pick Option C instead of D.
Detailed technical explanation
How to think about this question
Under the hood, the query uses the `SigninLogs` table where `ResultType != 0` captures all non-success codes (e.g., 50053 for account locked, 50055 for password expired, 50126 for invalid credentials). The `bin(Timestamp, 5m)` creates time windows, and `summarize` with `dcount(IPAddress)` ensures the same IP is driving the failures. In a real-world scenario, this query would miss distributed brute force attacks using multiple IPs (low-and-slow), but it effectively catches single-source password spraying or credential stuffing attempts.

Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
